无法在Java上使用@Factory testng批注运行并行测试

Question

So I use @Factory to run one test with 5 different emails, but I get wrong number of arguments exception and I can't see the full error trace on console. I use TestNG. Here's my code:

package com.task.lab.facadetask;

public class GmailTest {
    private WebDriver driver;
    private static List<User> usersList;
    static List<TestMessage> mess;

    public GmailTest(){}


    @Factory(dataProviderClass = GmailTest.class, dataProvider = "getData")
    public GmailTest(WebDriver driver,List<User> usersList, List<TestMessage> mess ){
        this.driver = driver;
        GmailTest.usersList = usersList;
        GmailTest.mess = mess;
    }

    @BeforeMethod
    public void setUpDriver(){
        driver = DriverObject.getDriver();
    }

    @DataProvider
    public static Object[][] getData() {
        File usersXml = new File("src\\\\main\\\\java\\\\com\\\\task\\\\lab\\\\facadetask\\\\testdata\\\\users.xml");

        try {
            usersList = JAXB.unmarshal(usersXml);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
        TestMessages messages =  UnMarshell.unmarshaller();
        assert messages != null;
        mess = messages.getTestMessages();
        return new Object[][]{
                {mess.get(0), usersList.get(0)},
                {mess.get(1), usersList.get(1)},
                {mess.get(2), usersList.get(2)},
        };
    }

    @Test
    public void testGmail(TestMessage message, User users) {
        String gmailURL = "https://accounts.google.com/signin";
        driver.get(gmailURL);
        Login loginPage = new Login();
        loginPage.login(users.getEmail(), users.getPassword());
        GmailMessage gmailPage = new GmailMessage();
        gmailPage.sendMessage(message.getReceiver(), message.getSubject(), message.getMessage());
        gmailPage.removeMessage();
        Assert.assertTrue(gmailPage.isRemoved());
    }
    @AfterMethod
    public void quitBrowser(){
        try{
            driver.close();
        }finally{
            driver.quit();
        }
    }
}

My assumption is that it could be caused by changing the original non static lists of users and messages to static, but DataProvider method needs to be static. Could someone guide me on what am I doing wrong? UPD:So, I removed @BeforeMethod and included driver in @DataProvider as Krishnan suggested but it gives me the same error, wrong number of arguments. Here's what the DataProvider starts with for now:

@DataProvider
public static Object[][] getData() {
    driver = DriverObject.getDriver();
    File usersXml = new File   //The rest remains the same

Also, I tried to initialize driver in BeforeMethod but in this case Test doesn't see it. It looks like this:

@BeforeMethod
public void setUpDriver(){
    WebDriver driver = DriverObject.getDriver();
}

Maybe someone can provide me with a valid analogue of Factory so I can run 5 parallel tests simultaniously? I am open for suggestions.

Answer 1

Your factory method is defined to accept 3 arguments.

@Factory(dataProviderClass = GmailTest.class, dataProvider = "getData")
public GmailTest(WebDriver driver,List<User> usersList, List<TestMessage> mess ){
    this.driver = driver;
    GmailTest.usersList = usersList;
    GmailTest.mess = mess;
}

Your data provider is only providing 2 parameters. WebDriver is not being provided by your data provider.

You can do one of the following :

• Either enhance your data provider to include the WebDriver object via a call to DriverObject.getDriver() and remove your @BeforeMethod method (or)
• Alter your constructor's signature to not accept a WebDriver instance, but initialize the class's WebDriver instance via the @BeforeMethod .

That should fix your problem.

EDIT: The question has been updated. So updating my answer as well.

Looking at the updates to the question, the answer is still the same on a high level. Now including a sample as well, which explains the answer.

Mocking how the User class could look like

import java.util.ArrayList;
import java.util.List;

public class User {
    private String name;

    public User(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public static List<User> newUsers(String... names) {
        List<User> users = new ArrayList<>();
        for (String name : names) {
            users.add(new User(name));
        }
        return users;
    }
}

Mocking how the TestMessage class could look like

import java.util.ArrayList;
import java.util.List;
import java.util.UUID;

public class TestMessage {
    private String text;

    public TestMessage(String text) {
        this.text = text;
    }

    public String getText() {
        return text;
    }

    public static List<TestMessage> newMessages(int howMany) {
        List<TestMessage> msgs = new ArrayList<>();
        for (int i = 0; i < howMany; i++) {
            msgs.add(new TestMessage(UUID.randomUUID().toString()));
        }
        return msgs;
    }
}

Here's how the test class should look like

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterClass;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Factory;
import org.testng.annotations.Test;

import java.util.Collections;
import java.util.List;

public class GmailTest {
    private WebDriver driver;
    private List<User> users;
    private List<TestMessage> testMessages;

    @Factory(dataProvider = "getData")
    public GmailTest(WebDriver driver, List<User> users, List<TestMessage> testMessages) {
        this.driver = driver;
        this.users = users;
        this.testMessages = testMessages;
    }

    @Test
    public void testMethod() {
        Assert.assertNotNull(driver);
        Assert.assertNotNull(users);
        Assert.assertNotNull(testMessages);
    }

    @AfterClass
    public void cleanupDrivers() {
        if (driver != null) {
            driver.quit();
        }
    }

    @DataProvider(name = "getData")
    public static Object[][] getData() {
        List<User> users = User.newUsers("Jack", "Daniel", "John");
        int size = users.size();
        List<TestMessage> testMessages = TestMessage.newMessages(size);
        Object[][] data = new Object[size][1];
        for (int i = 0; i < size; i++) {
            data[i] = new Object[]{new FirefoxDriver(), Collections.singletonList(users.get(i)),
                    Collections.singletonList(testMessages.get(0))};
        }
        return data;
    }
}

Here's the execution logs
